> > Any reason there isn't a sync in [`littlefs_truncate`](https://github.com/apache/nuttx/blob/90e9b2426d54682070b0fcc38ad5415bbf77f733/fs/littlefs/lfs_vfs.c#L929), > > good idea, patch is welcome. i agree it's a good idea to make O_TRUNC and truncate consistent. i don't think it's a good idea to make this hack in the first place though. it's better to leave it to user applications. my suggestion is to revert this PR to make it consistent. > > then? The woraround for users like me is to open the file without `O_TRUNC` and then call `truncate` to ensure no commit. > > but, the sync still need in open to ensure the truncate take effect immediately, but the sync could be called only when O_TRUNC is specified. a user application which needs the behavior can call fsync by itself. -- This is an automated message from the Apache Git Service.
